Syncmaster paower button blinking and no display

Hello,

This is a common problem with the Samsung 204B units that have been in service for a few years. Parts called capacitors in the power supply start failing and causing the board to not start correctly. The blinking power button is just the power supply restarting over and over. The monitor is easily repairable, you just need to replace the 5 capacitors that have failed. Here is a link to a page that shows how to open the monitor, get to the power supply board and what to replace.

in near your monitor u find any metallic product than you please remove the the monitor and plug in another side if your problems is steel not solved than you please contact samsung service center regarding this issue...........

Caps have completely flat tops, bad caps can also look normal but can have high ESR (Equivalent Series Resistance).<br /> What voltages are you getting at the secondary DC power supply side measure directly on those caps?<br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'"> <a href="http://s807.photobucket.com/home/budm/allalbums">http://s807.photobucket.com/home/budm/allalbums</a></span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'"><a href="http://en.wikipedia.org/wiki/Capacitor_plague">http://en.wikipedia.org/wiki/Capacitor_plague</a><span style="mso-tab-count: 1"> </span></span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: 'Arial','sans-serif'">Capacitors kit: <span style="mso-spacerun: yes"> </span><a href="http://lcdalternatives.auctivacommerce.com/">http://lcdalternatives.auctivacommerce.com/</a><span style="mso-spacerun: yes"> </span>he can make you a set of caps for you.</span><br />

Replace the screen with a known working one. If it shows display then it is the screen which is broken, if not, then it could be the port on which it is connected.

I suggest the power supply inside the monitor is bad.

Got the same problem, happened yesterday for me, Did some research and it looks like its bad capacitors in the back, check out this page for more information... i'm taking mine to an electrician to fix today... luckily he's related and should be able to fix it on the cheap...

Have you tried to plug it in else where?
If you did and still same problem then from what you said I was hopping that it wouldn't be your problem, but you will need a new monitor.
